This was a great game, you should make a second but possibly more upgrades. For example, with the wave rise maybe make 1 upgrade so that it gets bigger, and another so it moves slower or more then 2 comes out of it. Also, different kinds of levels, beginner, medium, hard, and maybe bonus for extra presents. 5/5 I loved it
